Patent JP-2001021525-A (JP)
Title: Measuring method using biosensor
Inventor: MORITA TAKASHI
IPC: G01N27/416
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To make a highly reliable measurement performable by measuring a current flowing between both electrodes, when impressing a rectangular-wave pulse voltage between a working electrode and a counter electrode. SOLUTION: The working electrode formed by immobilizing biocatalyst on an electrode composed of metal or carbon and a counter electrode are dipped in solution containing a measurement object substance, and a rectangular-wave pulse voltage is impressed between the working electrode and the counter electrode so that a voltage is impressed for an extremely short time. This method can drastically shorten the time impressing the voltage between the both electrode so as to measure highly precisely with hardly affected by the states of the solution and the measurement system. Preferably, the pulse width of the pulse voltage is 0.1-10 seconds then.  The potential difference generated between the both electrodes may be measured in making the rectangular-wave pulse current to blow between the both electrodes instead of measuring the current flowing between the both electrodes, when impressing the rectangular-wave pulse voltage between the both electrodes by this method.

Title: Semiconductor laser device
Inventor: TAGUCHI KINYA
IPC: H01S5/00
Filed: 1987-07-28
Abstract: PURPOSE:To increase scanning speed without augmenting the number of revolutions of a rotating polygon mirror by vibrating a semiconductor laser chip by a piezoelectric element and vibrating laser beams emitted from the semiconductor laser chip at constant frequency. CONSTITUTION:Voltage having constant frequency is applied to a piezoelectric element 6 set up under a semiconductor laser chip 7. Thickness is displaced in the vertical direction to the surface of a package-stem 5 by a reverse piezoelectric effect in the element 6, and the element 6 is vibrated minutely at fixed frequency in the direction. Since chip 7 itself is also oscillated, laser beams L are also vibrated minutely at constant frequency in the vertical direction to the surface of the stem 5. Laser beams L are made to scan in the main scanning direction of a photosensitive drum through an imaging lens by a rotating polygon mirror. Accordingly, scanning speed is increased without elevating the number of revolution of the rotating polygon mirror.

Title: Record density controlling device
Inventor: HOSOI MASATOSHI
IPC: G03G15/00
Filed: 1983-10-12
Abstract: PURPOSE:To maintain record density always within a specified range by holding the number of times of operation of the device, reading the state of change electrically and checking the density at every specified number of times of recording regardless of on/off of a power source. CONSTITUTION:A photosensor PS2 connected to the input port P1 of a microcomputer CPU outputs a timing pulse corresponding to rotation of a photosensitive drum 3. An electric contact connected to an input port P2 is provided in a stepping relay MME. Detected density data obtained from a converter ADC is compared with reference data, and when thin, a toner supply plug is set to 1, and when not thin, set to 0. When a movable terminal TC of the stepping relay MME is advanced by 1 step after completion of copy cycle, advance is made by 1 step every time recording is made. Accordingly, the input port P2 necessarily becomes low level L once when 10 times of recording are made, and it means that record density is checked always at a fixed period. The state of the stepping relay delay does not change even when the power source is cut off.

A control section 1 measures revolutions from count output of the counter 12 while judging that no disconnection occurs if the output of the waveform shaping circuit 11 is at the H level. On the other hand, when the output thereof 11 is at the L level, the continuation time at the L level is measured and when the time exceeds the specified value, the occurrence of a disconnection is judged to output a disconnection signal.

Title: Developing device for electrostatic latent image
Inventor: INUI YASUO
IPC: G03G15/08
Filed: 1985-08-29
Abstract: PURPOSE:To uniform image density, specially, right-left density difference by adjusting independently potentials applied to electrodes at both ends of a sleeve so that optional potential difference is generated between both ends of a conductive developing roller. CONSTITUTION:When a changeover switch 20 is as shown in a figure, a circuit is formed extending from a high voltage variable power source 19 to an electrode 8E, a sleeve end 15, a resistance 17 (sleeve), a sleeve end 16, and electrode 8A, a variable resistance 18, and then an earth point successively. Therefore, when a voltage V1 is outputted from the power source 19, a voltage drop is caused at one sleeve end 16 by a current flowing through the sleeve and the voltage at the end part 16 becomes V1R2/(R1+R2). Thus, a potential with an optional level and an optional gradient, i.e. optional developing bias is obtained by varying the output V1 of the variable power source 19 and variable resistance R2 or reversing the right and left potentials of the resistance 17 (sleeve) through the operation of the switch 20, so the density of the whole image and the right- left density difference are adjustable.
